Sterilizing Press Assembly for Contamination-Free Combination Lids
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for sterilizing components with enclosed cavities, such as combination lids, fail to achieve full sterilization without causing secondary contamination due to assembly after sterilization.
Innovation Solution
An integrated machine with a sterilization case and pressing devices, including an outer cylinder, inner cylinder, material mold, and pressing plates, allows for simultaneous sterilization and pressing within the same chamber, utilizing a block pressing method and servo electric cylinders for precise control, and a stress sandwich layer for structural stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If components are sterilized first and then assembled, then sterilization completeness is improved, but secondary contamination occurs after assembly
Solution Approach 1:
The patent combines the sterilization chamber and pressing chamber into a single integrated machine. The sterilization case includes an outer cylinder and inner cylinder that serve as both sterilization and pressing chambers, allowing components to be sterilized and assembled without leaving the sterile environment. This eliminates the need to transfer sterilized components to an external assembly area, thereby preventing secondary contamination while maintaining sterilization completeness.
2Reliability
If traditional sterilizer is used for sterilizing components, then sterilization is achieved, but assembly and pressing require separate operations causing time loss
Solution Approach 1:
The integrated machine merges sterilization and pressing operations into a single device. After components are sterilized in the sterilization case, the pressing devices can directly press the components within the same chamber without requiring transfer to another machine. This eliminates idle time between sterilization and assembly operations, significantly improving production efficiency while maintaining sterilization effectiveness.
Solution Approach 2:
The design enables continuous operation where sterilization and pressing occur in sequence within the same chamber without interruption. The pressing devices are positioned inside the sterilization case, allowing immediate transition from sterilization to pressing operations, thereby maintaining continuous productive action and eliminating downtime associated with transferring components between separate machines.
3Reliability
If inner cylinder is made porous for sterilization, then sterilization penetration is improved, but connection strength between inner and outer cylinder decreases
Solution Approach 1:
The inner cylinder is divided into multiple porous sections or layers, each with controlled porosity to allow sterilization penetration while maintaining structural integrity. The segmentation allows optimization of different regions for different functions - some areas with higher porosity for sterilization access and other areas with stronger connections for structural support, thereby balancing sterilization effectiveness with mechanical strength.
